osornra'rrne WHEEL arm marvma MECHANISM} To all 10 from it may concern Be it known that I, EDWIN J. GOULD, a citizen of the United States, residing at Oakland, county of Alameda, State of California, have invented certain-new'and useful Improvements in Oscillating Wheels and Driving Mechanism, whereof the following is a specification. t

My invention relates to improvements 111 motor vehicle wheels andv consists of a combined oscillating wheel and. driving mechanism, and the object of my improvementsare, to provide a vehiclewheel that will oscillate upon striking an obstruction, combined with a driving mechanism, that wlll freely allow such oscillation and. will at the same time exert the full driving power on the wheel in any position the wheel may assume in oscillating, or even allow the wheel and stub axle to which it is attached, to make a complete circuit around the drivlng axle. Further objects and advantages of the invention will be brought out in the specifications and the novelty of construction will be particularly pointed out in the claims.

I attain these objects by the mechanlsm illustrated in the accompanying drawings in which-Fig. 1 is a view in elevation of the device with vehicle wheel attached; Fig. 2 is a View in elevation at right angles to Fig. 1 showing the drive disks and collar in section; Fig. 3 is a View of the drlvlng mechanism the dotted lines showing different positions assumed in oscillating.

Similar numerals refer to similar parts throughout the several views. 1 is drive axle of motor vehicles shown encased n housing and connected to differential; 1s drive disk keyed to the drive axle; 3 1s a similar drive disk keyed to a stub axle; 4 are the pitmen, in this construction four are used connecting disk 2 with disk 3; 5 indicates one of the studs revolubly connecting the ends of the pitmen to the disks 2 and 3; 6 is a stub axle to which disk 3 s keyed, and to which the vehicle wheel 1s also solidly attached; 8 is acollar 1n whlch stub axle 6 revolves; 99 are arms extending from and forming part of collar 8; 10-10 are springs one end of each spring being attached to one of the arms 9 and the other end of each spring being attached to the frame of the vehicle; 11 is a band brake surrounding the disk 2 and adapted to bring friction to bear on the rim of said disk in Speeificati'onof Letters Patent. patgnted A Application filed June 18 1921.. Serial No. 478,723.

the usual mannerwhen acting as a brake tothe vehicle.

In operation when power is applied to the dr ve axle 1, drive disk 2 being keyed to the drive axle rotates, and through the pitinen 4 connecting it with disk 3 rotates disk 3. Disk 3 being keyed to the stub'axle 6, and

the vehicle wheel 7 being solidly attached to the opposite end of the stub fore rotated same direction as the driveaxle 2. The collar 8 (in which the stub axle 6 revolves) is attached by the coil springs axle '6 is thereagainst side sway and holding the wheel in alignment when the weight of the vehicle is thrown mostly on the wheels on one side, at the same time the pitmen act as a perfect gearless drive transferring power to the wheels with the minimum of loss and also allows the vehicle wheel and stub axle to which the wheel is solidly attached to make a complete circuit around the drive axle when the wheel goes over an obstruction, adding greatly to the efiiciency and capacity in eliminating all shock and jar from the veat the same speed and in the 10-10 to the frame of the vehicle, and when the springs hicle. This construction is easily adapted to the combination with any material change the brake.

I reserve the right to make any modifications in construction that may properly come within the protection prayed.

Having thus described my invention what I claim is,

1. The combination in an oscillating wheel and driving mechanism, of a disk and pitman drive, a means for rotatin one disk of said drive, a stub axle attache to the other disk of said drive, a wheel attached to said stub axle, a collar in which said stub axle revolves, and springs attaching said collar to the vehicle frame in such manner as to a band brake, without in the construction of and drivin mechanism of a'disk and pitman of said drive,

1101a said stub axle beneath the driving axle and at the same time allow said stub axle and attached wheel to oscillate, backward and upward whenever said wheel encounters an obstacle.

2. The combination in an oscillating wheel drive, a stub axle attached to one disk of said drive, a wheel attached to said stub axle, a collar in which said stub axle revolves, springs attached to said'collar in such manner as toallow said stub axle to oscillate and a hand brake fitted to one disk of said drive substantially as set forth.

, 3. The combinationin an oscillating wheel and driving mechanism of a disk and pitman drive, a driving axle for rotating'one'disk afstub axle solidly attached to the other disk of said drive, a wheel solidly attached to said stulo' axle, a collar surro-unding said stub axle, springs connecting said collarto a vehicle frame in such manner as to hold said stub axle lower than the driving axle and at the same time allow said stub axle and wheel make a complete circuit" hicle in such manner as to allow the wheel tooscillate or make a complete circuit around the first named disk while being driven.

In'testimon-y that I claim the foregoing,

I have hereunto set my hand in the 'pres-' enceoftwo witne'sses, this 8th day-of April, 1921. g i g a EDWIN J. GOULD. I Witnesses: g I
